Plato/philosophy

Famous quotes containing the words plato and/or philosophy:

“Man is the measure of all things; of that which is, that it is; of that which is not, that it is not.”
—Protagoras or Plato (c. 490–421 B.C.)

“The very hope of experimental philosophy, its expectation of constructing the sciences into a true philosophy of nature, is based on induction, or, if you please, the a priori presumption, that physical causation is universal; that the constitution of nature is written in its actual manifestations, and needs only to be deciphered by experimental and inductive research; that it is not a latent invisible writing, to be brought out by the magic of mental anticipation or metaphysical mediation.”
—Chauncey Wright (1830–1875)
